[Also in Division F1] A process for maintaining under vacuum a chamber (not shown) connected to a source of gas, comprises causing the gas introduced into the chamber to solidify on refrigerated plates 3, 5 or 4, 6 associated with cryopumps, 1, 2 connected to the chamber, liquefying the solidified gas by warming up the refrigerated plates, discharging the liquefied gas through conduits 17 or 18 for subsequent utilization as a refrigerant for cooling directly or indirectly the chamber. The chamber to be evacuated is alternately connected to cryopumps 1, 2 and, as shown, the cryopump 1 is connected to the chamber and is arranged to solidify the gas introduced thereto while the other cryopump 2 is discharging liquefied gas to a storage vessel 20. Nitrogen refrigerant is supplied to the plates 5 and passes therefrom through lines 65, 69, 71-74 and through heat exchangers 28, 23 to a compressor 21 having a branched outlet, whereby part of the nitrogen is cooled in a heat exchanger 24 and part is cooled in the heat exchanger 23 to pass thereafter to the heat exchanger 28 and an expansion machine 26 from which it joins nitrogen vapour given off from the nitrogen in the vessel 20 and recycled refrigerant from the conduit 69. The cooled pressurized nitrogen leaving the heat exchanges 24, 28 is expanded in a valve 30 and passes to the vessel 20 from which it passes via a conduit 60 back to the plates 5. The refrigerant circuit for the hydrogen which cools the plates 3, 4 comprises a line 97 connected to the plates 4 of the cryopump 2 undergoing defrosting, a heat exchanger 42, a line 98, a compressor 40, exchangers 42, 44, 46, 51, 56, 58, expansion turbines 48, 53 and a return line 59. In the cryopump 2 defrosting is achieved by supplying a defrosting coil 8A with low pressure hydrogen warmed in the exchanger 44 and re-cycled through the plates 4 to the line 97 and the compressor 40.

IPC: B01D51/10
Filed: 1969-08-25
Abstract: 1,260,895. Drying compressed gases. DELTECH ENG. Inc. 25 Aug., 1969 [17 Feb., 1969], No. 42304/69. Heading B1L. [Also in Divisions F3 and F4] Compressed gas to be dried is conveyed via line 18, Fig. 2, to a chiller 10 where it heat exchanges with refrigerating fluid passing in a closed refrigeration system. Heat is given up to the refrigerating fluid which evaporates, whilst water condenses from the compressed gas and is removed by separator 20 and drain 12 before the gas passes to a reheater 11. The evaporated refrigerating fluid passes via a compressor 13 to point 26 whereupon it divides into conduits 27 and 29. (The amounts passing in these conduits depend upon the relative heat fluxes involved in the heat exchanger and are self adjusting). The evaporated compressed refrigerating fluid passing in conduit 27 gives up heat to the cool dry gas in the reheater 11 which then leaves via pipe 21 whilst recondensed refrigerating fluid leaves via conduit 28 and meets, in chamber 16, with that part which divided at 26 and was recondensed by an air condenser 14 and fan 15. The fluid recycles via expansion valve 17. In a modification, Fig. 3, the chiller 10a and reheater 11a, which have their refrigeration fluid paths connected by a refrigerating fluid expansion capillary coil 17a, are enclosed in a tube 45 and connected in series with a compresser 13a and air condenser 14a. Conduit 58 and bypass valve 59 provide a refrigerating fluid shunt path. The tube 45 can be transparent so that a humidity indicator can be observed. Several such chillers and reheaters can be used.

Abstract: 1,137,980. Welding by pressure; soldering. P. OPPRECHT. 23 Sept., 1966 [24 Sept., 1965], No. 42626/66. Heading B3R. In joining overlapped sheet metal edges of which the facing surfaces are coated with low melting-point metal the overlapped edges are resistance welded by wire-like electrodes having a small contact area with the outer surfaces of the overlapped edges and advancing with the edges and after being welded the edges are squeezed together so that the melted lower melting-point metal is distributed to reduce the risk of corrosion after it has solidified. Tinned or galvanized sheet iron shaped to form a can body is introduced with its edges 44, 46, Fig. 4, between the electrode rollers 5, 7, Fig. 1, of a welding machine having a wire 9 forming a moving electrode surface passing over each of the rollers 5, 7. The electrode 7 is carried on a lower fixed arm 1 and the electrode 5 is on a pivoted upper arm 3 and lower roller 19 is carried on bracket 21 on the arm 1 to cooperate with a roller 15 on a pivoted arm 13. The roller 15 is driven from the electrode roller drive but both rollers may be driven. The can body passes between the rollers 5, 7, whereby the weld 48 is produced and the welding heat causes melting of the tin coating which flows between the overlapped part 44, 46 pressed together by the rollers 15, 19. The can body then passes a nozzle 23 which sprays a protective film 52. In a modified machine the rollers for exerting pressure subsequent to the electrode rollers are both idlers. A separate heating source may be provided between the electrode rollers and the pressure applying rollers and both sides of the overlapped edges may be sprayed with the protective film.
